Question

10. Two plane mirrors are kept at an angle of 90° to each other. If an incident ray makes an angle of 60° with
the first mirror as shown in the figure, then find angle of incidence & angle of reflection for both the mirrors​

Answer 1

For Plane Mirror 1: i=r=30°

For Plane Mirror 2: i=r=60°

Answer 2

Answer:

Angle incident ray made with the mirror =60 degree.

Drawing normal on the point of incidence, we get angle of incidence =90-60=30 degree.

Since angle of incidence is equal to angle of reflection, angle of reflection =30 degree

Reflected ray of first mirror becomes incident ray for the second mirror,

So angle of incidence =angle of reflection =30 degree.
